荷电电压、介质物性对静电雾化特征的影响
Effects of liquid properties on electrostatic spray characteristics
摘要
Abstract
Experimental investigation was performed for electrostatic spray of several spray liquids under capillary-annular electrode configuration. The effects of the material properties of the spray liquids and electrode voltage on electrostatic spraying were analyzed through the working parameters of charge-mass-ratio ( CMR). Experiments show that in the case of micro-flow rate ranges, there is almost a linear growth of the applied voltage and the CMR before Rayleigh limit within the right voltage range. Spray liquid electrical conductivity has a great influence on the charge-mass-ratio, the higher the spray liquid electrical conductivity is, the faster the CMR of drops with the electrode voltage increases, and when it is lower, the applied voltage plays a leading role on the CMR. The CMR response is inversely proportional to spray liquid viscosity but proportional to spray liquid surface tension.关键词
